Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0015] The vacuum transport tank consists of eight parts, including the vacuum tank body 3, the vacuum tank cover 7, the vacuum tank base 1, the support column 2, the sample cup 4, the fastening mechanism 8, the valve and the exhaust pipe 9, and the opening mechanism 5. Linear bearing 6 and sealing ring 10. Except for the standard linear bearing parts 6, springs, fastening screws and standard parts sealing ring 10, the remaining parts are all independently designed and assembled as a whole, made of metal. The purpose of the whole made of metal is to conduct electricity so that the electron beam can work continuously.

[0016] The vacuum tank body 3 is used to load the sample cup 4 and maintain the vacuum. A sealing ring 10 is provided between the vacuum tank body 3 and the sample cup 4 for sealing; each sample cup 4 can be designed according to requir...

Abstract

The invention belongs to the technical field of vacuum device design, and particularly relates to a vacuum transportation tank for electron-beam encapsulation. The vacuum transportation tank comprisesa vacuum tank body, a vacuum tank cover, a vacuum tank base, a support column, a sample cup, a fastening mechanism, a valve and a suction pipe, an opening mechanism, a linear bearing piece and a sealing ring. The vacuum transportation tank is simple and reliable in design and convenient to operate; the vacuum tank body is sealed and vacuumized by bolts and rubber rings, so that good protection ofsamples from oxidation can be realized; and vacuum packaging materials can be opened quite conveniently during electron beam welding, and thus the operation cost is saved.

Description

Technical field [0001] The invention belongs to the technical field of vacuum device design, and specifically relates to a vacuum transport tank for electron beam packaging. Background technique [0002] At present, for the welding and packaging of anaerobic materials (such as metal powders and alkali metals with high purity requirements), these materials are generally pre-loaded in the sheath and evacuated, and then the exhaust pipes connecting the sheath are welded together. This ensures that these anaerobic materials are in a vacuum state and can be transported to the next processing step. However, this packaging method still has some problems, which are mainly reflected in the low efficiency of vacuuming the envelopes one by one; and the existence of huge pressure differences when the welding control is unstable will cause air to squeeze into the envelope and reduce success. Rate and cause sample contamination. Therefore, in the case of particularly high requirements for va...
